A novel porous metal-organic framework (MOF), pCu-BDC-NH2, with hierarchical porosity was synthesized using cetyltrimethylammonium bromide (CTAB) as a pore-generation agent. In addition to its common functions including structure-directing ligands or soft micelle templates, the judicious use of CTAB effectively modulated pore architecture in Cu-BDC-NH2 MOFs. With additional mesopores generated during synthesis process, intrinsic MOF scaffolds further obtained hierarchies and interconnectivity, enabling efficient substrate access active metal centers, thus significantly facilitated catalytic performance. As proof concept, we applied finely engineered pCu-BDC-NH2 cascaded enzymatic system for xanthine sensing. This colorimetric biosensor exhibited low detection limit 0.11 μM, wide linear range 1–120 μM. Furthermore, sensor demonstrated exceptional stability, reproducibility, independent interferences. Our simple yet effective method may find broader applications tailoring architecture, finer structures improve activities nanomaterials.
